VANCOUVER, British Columbia — Darren Mattocks scored for the fourth time in the last five games to help the Vancouver Whitecaps beat Sporting Kansas City 2-0 in Major League Soccer on Sunday.

The Whitecaps took the lead in the 17th minute when Sporting defender Igor Juliao and goalkeeper Andy Gruenebaum got their signals crossed after Vancouver's Pedro Morales lofted a long ball toward goal. Juliao tried to head a pass back toward Gruenebaum, but it dribbled over the line.
